硫酸钠型矿卤除硫的工艺研究

Study on the Process of Sulfur Removal from Sodium Sulfate Brine

矿卤日晒盐,获得了巨大的发展,但是由于矿卤富含硫酸钠,给原盐生产带来了困难。如何有效的利用钙液除硫,一直有争论。在此背景下,对硫酸钠型矿卤的除硫工艺进行了研究,最终确定了老卤除硫的循环利用生产工艺。

Solar salt from brine has been obtained great development, but still brought diffi- culty to salt production as rich sodium sulfate. Therefore, it is always debated how to effectively re- move sulfur with calcium chloride. The process of sulfur removal from the sodium sulfate typed brine was investigated. Finally, the recycling production process by removing sulfur from old brine was determined.
